Snow and ice anti-skid devices for shoes

ABSTRACT

A novel cleat securable to the underside of a shoe in order that a person wearing the same can walk on slippery surfaces without slipping; the cleat in one form of the invention consisting of a pair of metal bars connected pivotally together at their centers, one end of the bars being bent to clamp around a shoe sole, and the other end being connected to an elastic band extending around the shoe heel, the underside of the bars having projections for frictionally engaging a walking surface; and the invention in another design consisting of a rotatable roller having a row of projections that are rotatable between a utility and retracted position.

1 Claim, 4 Drawing Figures SNOW AND ICE ANTI-SKID DEVICES FOR SHOES Thisinvention relates generally to shoe cleats.

A principal object of the present invention is to provide an anti-skiddevice mountable under shoes so that a person can walk on snow and icewithout danger of slipping and falling down.

Another object is to provide a snow and ice anti-skid device for shoeswhich can be quickly installed on the shoes when wanted, and which isthen readily removable when no longer needed.

Yet another object is to provide a snow and ice antiskid device forshoes which is self-adjustable to fit all sizes of footwear.

Other objects are to provide a snow and ice anti-skid device for shoeswhich is simple in design, inexpensive to manufacture, rugged inconstruction; easy to use, and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing, wherein:

FIG. 1 is a top view of one design of the invention.

FIG. 2 is a side view thereof.

FIG. 2a is an end view thereof.

FIG. 3 is a bottom view of a modified design of the invention shownsecured to an underside of a shoe.

Referring now to the drawing in detail, and more particularly to FIGS. 1and 2 at this time, the reference numberal represents a snow and iceanti-skid device according to the present invention, wherein there is aroller-shaped member 11 having a single row of pointed projections 12 onits underside. A shaft 13 is secured fixedly to one end thereof, and athreaded shaft 14 is screw-thread into an opposite end thereof.

The shaft 13 extends through a bracket 15, while shaft 14 extendsthrough a bracket 16. The bracket 15 is affixed to the underside of atop plate 17 having a clamp 18 formed at one end. The bracket 16 isaffixed to the underside of a top plate 19 having a clamp 20 formed atone end. The top plate 17 adjustably overlaps the top plate 19 and isselectively securable thereto so to adjust to shoe width, by means ofadjustment screws 21 passed through slots 22 of top plate 17 and intothreaded openings of top plate 19. The clamps serve to grip around theedges of a shoe sole. The threaded shaft 14 has a knurled head 23 foreasy turning, the shaft extending through a wafer washer 24. A lockingdevice 25 is affixed to shaft 13 and is associated with a spring steelspring leaf 26, so to maintain the locking device locked in eitheropening 27 or 28. When the locking device is in the position as it isshown in FIG. 22, the projections 12 extend downward for use; when thelocking device engages opening 28, the roller member is rotated so theprojections extend generally horizontally retracted by pointing toward aheel. To adjust the device to fit a shoe, the screws 21 are firstloosened before turning the knurled screw head 23.

In FIG. 3, another design 29 of the invention consists of metal bars 30pivotably attached on a common rivet 31. An upward clamp 32 is on oneend of each bar, and the other ends are attached to opposite ends of anelastic band 33 placeable around a shoe heel 34. The elastic bandmaintains forces of the clamps 32 grip around opposite side edges ofshoe sole 35. Downward projections 36 on the bars serve to grip a snowor ice surface.

We claim:

1. In a snow and ice anti-skid device for shoes, the combination of ameans for securement of said device to an underside of a shoe sole, andmeans for frictionally engaging an icy or snowy surface, said securementmeans including a pair of clamps for grasping around opposite side edgesof said shoe sole, said engaging means comprising a plurality of pointedprojections, said projections forming a row along a rotatable roller,said projections being on an underside of a pair of bars attachedscissors-like together and normally urged closed by an elastic band.
